Zone 1 Tube station on the Bakerloo, Jubilee, Metropolitan, Circle, and Hammersmith & City lines.

It has entrances on both the north and south sides of Marylebone Road, but the southern entrance (at the corner of Chiltern Street) is sometimes closed outside peak hours. However, the foot tunnel connecting the two sides of this busy thoroughfare (closer to the junction with Baker Street) is always kept open.
